Event viewer(System)
 

Good day!

im using windows xp-sp2,when I try to save an shared excel(excel2000-sp3)
file on the network,i cannot click the standard button on the excel, the
file menu,etc.
i check the task manager all application are running.
then i check the event viewer, on system, i have this warning - "The
redirector failed to determine the connection type."

What does it mean?
